Hi,

Thanks for this. One point raises some questions in my mind:

I am wondering why, in this case, Intent would be broadcasted in
a single operation as a single file. Why wouldn't we simply send out
each section separately?

Also, how is the relevance for each ASA known? And is that the correct
granularity of the section? Maybe the granularity should be individual
objectives, or certain groups of objectives? I think this needs more
discussion.

Regards
   Brian
